Legal Hold Confirmation Page: There is a problem with this website's security certificate

I am configuring the Legal Hold confirmation server on a new Clearwell v7.1.2 install. By default, links to the confirmation webpage are configured as HTTPS, so when a custodian clicks on a Legal Hold confirmation link, they get this message:

There is a problem with this website's security certificate.

The security certificate presented by this website was issued for a different website's address.

Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server.

We recommend that you close this webpage and do not continue to this website.

Continue to this website (not recommended).

More information

We will not be deploying a certificate since all access is internal. The Legal Hold guide suggests two methods to create a certificate but there is a property that will direct the user to a non-secure version of the Confirmation Server, an HTTP address instead of an HTTPS, that will eliminate this error.

My question is seeing as it is internal only and you are being redirected to HTTP anyway why have it use HTTPS at all?

The redirect removes any security that you were hoping to get through HTTPS

I think if HTTPS is needed then installing a full certificate not a self-signed one will not only remove the certificate warning message in IE but it will also ensure that the users are reaching a secure site and any communication is secure.
